8 Claims. 139-195) This invention pertains to looms and moreparticularly relates to selvage kdevices therefor.

It is general practice in weaving cloth to add eXtra ends in the selvageto carry the strain or jerk of the iilling yas the shuttle is pickedacross to the opposite side of the loom. Various types of selvagedevices have been employed to eliminate the necessity of having theeXtra ends for the protection of the lling. Such prior devices usuallycomprise a support mounted on the loom temple head and having a needleor loop retaining rlngerpivotally connected thereto and when inoperative position projecting down past the selvage at the point Wherethe filling is beaten up, so that the shuttle draws the lling around theneedle until it arrives at the box on the other side, when the needle israised to inoperative position.

In such devices it is essential that the needle, when raised toinoperative position, not interfere with the proper operation oi thereed or other parts of the loom.

Accordingly it is the principal object of my invention to provide in aloom, a selvage device comprising a support including a housing adaptedto be attached to the loom temple, a reciprocating member mounted in thehousing and having a needle at one end and resilient means for holdingthe reciprocating member in its rearward position, which reciprocatingmember shall be connected to the housing by a pin and slot connection soconstructed and arranged as to give the member a swinging movement in avertical plane and then a reciprocating movement in a horizontal planewhereby the needle will be iirst lifted clear of the warp threads andthen moved forwardly out oi the way or" the reed.

The foregoing and other objects of the invention are accomplished in theconstruction illustrated on the accompanying drawing, of which:

Fig. l is a perspective View of a portion of one end of a loom having myinvention applied thereto; i

Fig. 2 is a view in cross-section taken on line 2-2 of Eig. 1 andshowing the needle in its operative position;

Fig. 3 is a view similar to that of Fig. 2, but showing the needleraised to inoperative position; and,

Fig. 4 is a view similar to that of Fig. 2, but shows the needle raisedto inoperative position and moved to its forward position. l As `theinvention is applicable to any type of loom wherein there is a frame, alay, shed forming mechanism, a shuttle and shuttle picking mechanism,and other usual instrumentalites, it is considered unnecessary toillustrate such fea-V tues which are familiar to those skilled in the arAccordingly only a small portion of the right hand side or" a loom isshown, including the right hand loom temple on which the selvageV deviceis mounted. As the construction is generally similar at both sides ofthe loom ity isconsidered suicient only to refer to that of one side.

On the drawing is shown a portion of the usual lay i, hand rail 2,V reed3shuttle guard rail. 4 and the right handvtemple 5.

The selvage device of myv invention is shown as mounted on the templehead `and may comi prise a housing indicated generally at 6. The housingmay be formed as a single integral piece or may be made in two separatepieces as shown on the drawing.V The housing may comprise a pair ofspaced plates 'l and 8. 'Ihese plates are held apart by the spacing lugs9 and I0 which are formed integralvwith plate l. A bolt Il securesplates 'I and 8 together. A pin I2 formed integral with plate 8,projects into an opening in plate l, for a purpose to be hereinafterdescribed. Plate 8 has formed integral therewith and substantially atright angles thereto an attaching portion I3. The attaching portion I3has an elongated opening therein for the reception of a bolt I4 by meansof which the housing is adjustably attached to the head i5 of the temple5. The plate I has an extension I5" extending outwardly from its upperedge for a purpose later to be described.

By means of the spacing lugs 9 and ItY and the bolt II, plates I and 8are rmly heldr together in parallel spaced apartv planes formingtherebetween a guide-way or passage way Il.

Mounted in guidepassageway Il in housing 6 for-reciprocatory movementtherein is amenivber I8. Member `I8 has an upstanding lug I9 at one end.Lug I9 has an opening therein for the reception of the threaded arm 2Uof a bunter 2i. BunterV 2| is adjustably secured toY lug' I9 by means oflock nuts 22, 23. Member I8 at its other end has an opening 2li for thereception e of `a needle bar 25. Needle bar. 251s adjustably secured .tomember Ill-by means of setv screw 26. Needle bar 25 may carry oneor morespaced needles 2l.` Member I8 hasformed on its bottom side andintermediate its ends an open ended slot or recess 28. Vlin I2 whichextends f transversely ofthe guideway I'I4 is located within slot 28'and bears 'against the upperl'wall oi slot 28 thereby guiding andsupporting member I8 in its reciprocatory movements; in addition pin I2forms a pivot about which member I8 may be swung in a vertical plane,that is when member I8 has moved rearwardly and pin I2 rests against theclosed end of slot 28.

The bolt II in addition to its function of securing plates 'I and y8together, acts as a stop to limit the downward movement of member I3 asit swings in its vertical arc. Bolt I I also acts as a supporting andguiding surface for member I8 on its reciprocatory movement. Theextension I6 on plate 'I acts as a stop to limit the upward swing ofmember I8.

A coiled spring 29 has one en d secured to eX- tension I6 as at 30 andthe other end secured to lug I9 as at 3|. The function of spring 29 isto urge member I8 rearwardly in guideway I'I until pin I2 abuts theclosed end of slot 28, then the spring causes member I8 to swing aboutpin I2 as a pivot, the rearward end of member I8 which carries theneedle bar moving downwardly until it abuts bolt I I.

The operation of the device is as follows:

The device is adjustably mounted on the temple so that when the needle21 is in its lowermost or operative position, the point of the needle isbetween the warps, adjacent the selvage just behind the beaten in weft.When the shuttle is picked across the warps from that side or selvage ofthe fabric, the weft will loop about the needle and will'be held therebyagainst being pulled inwardly. When the lay moves forwardly to beat inthe weft the shuttle guard rail 4 will engage the bunter 2I and againstthe pull of spring 29 will swing member I8 about pin I2 as a pivotthereby raising the needle 21 upwardly from the warp. When the forwardend of `member I8 abuts the stop extension I6, the upward swingingmovement stops and as the shuttle guard rail 4 continues to moveforwardly member I8 will slide forward in guideway I'I against the pullof spring 29. Member I8 in its forward movement slides on and issupported by pin I2. Upon the rearward movement of shuttle guard rail 4,the spring 29 slides the member I8 rearwardly until pin I2 abuts theclosed end of slot 28 whereupon the spring causes member I8'to turnabout pin I2 as a pivot thereby lowering the needles 21 into operativeposition. W'hen the needles are in operative position the rearward endof member I8 abuts the bolt II which acts as a stop limiting thedownward movement of member |18.
